🔌 CONVERT 24V DC TO A REGULATED 12V-CLASS SUPPLY

The Orion is designed for installations where a nominal 24V DC system needs to operate equipment requiring a lower 12V-class supply.

Input voltage range: 18V–35V DC

Adjustable output range: 10V–15V DC

Supplied factory/set value: 13.2V

This adjustable design provides greater flexibility than a fixed-output converter and allows the output to be configured for compatible accessories, electronics or approved battery-buffering applications.

⚠️ IMPORTANT: Confirm the required voltage of connected equipment before adjustment or connection. Incorrect output voltage can damage connected electrical equipment.

---

🎛️ ADJUSTABLE 10–15V OUTPUT

The converter includes an adjustable output controlled by a potentiometer.

Output-voltage range:

10V–15V DC

Supplied set value:

13.2V DC

The adjustable output allows the converter to be tailored to compatible applications requiring different regulated voltages within the supplied range.

⚠️ IMPORTANT: Measure and correctly set the output voltage before connecting sensitive equipment or a battery.

---

⚡ 25A CONTINUOUS OUTPUT

Continuous output current:

25A

Maximum output current:

35A

The 25A continuous rating should be used when calculating normal sustained loads.

⚠️ IMPORTANT: The supplied 35A figure is the maximum output-current rating and should not automatically be treated as a continuous operating specification.

---

📈 96% HIGH-EFFICIENCY CONVERSION

Supplied efficiency:

96%

High conversion efficiency helps minimise power losses between the 24V input system and regulated lower-voltage output.

This can be particularly beneficial in battery-powered vehicle, marine and auxiliary systems where available energy and heat management are important.

---

🔋 BATTERY BUFFER-CHARGING CAPABILITY

The supplied product information states that Orion models with adjustable output can also be used as battery chargers or for buffer-charging compatible batteries.

A specifically supplied example is charging a 12V starter or accessory battery in an otherwise 24V electrical system.

The adjustable 10–15V output allows the converter voltage to be configured to suit an approved battery application.

⚠️ IMPORTANT: Battery charging voltage depends on battery chemistry and manufacturer requirements. Set the converter correctly for the battery being used and confirm that buffer charging is appropriate for the application.

⚠️ IMPORTANT: Do not assume one voltage setting is suitable for AGM, GEL, flooded lead-acid and lithium batteries. Always follow the battery manufacturer's charging requirements.

---

🎛️ REMOTE ON/OFF CONTROL

The Orion includes a remote on/off connection.

This eliminates the need to install a high-current switch directly in the converter's main input wiring.

The remote on/off may be operated using a suitable low-power switch or compatible engine run/stop signal.

This can make the converter easier to integrate into vehicle and machinery electrical systems where automatic operation is required.

⚠️ IMPORTANT: Follow the applicable manufacturer wiring instructions when connecting the remote on/off function or integrating it with an engine run/stop circuit.

---

🔗 CONNECT UP TO FIVE UNITS IN PARALLEL

The supplied product information states that adjustable-output Orion models can be connected in parallel to increase available output current.

Up to five compatible units may be connected in parallel.

This can be useful where one 25A converter does not provide sufficient continuous output current for the application.

⚠️ IMPORTANT: Parallel installations should follow the manufacturer's requirements, including correct output-voltage matching, cable sizing and circuit protection.

---

⚡ UNDER-VOLTAGE SHUTDOWN & RESTART

Under-voltage shutdown:

14V

Under-voltage restart:

18V

The converter is designed to stop operating when input voltage falls below the supplied shutdown threshold and restart once sufficient input voltage has returned.

This helps prevent continued operation when the input supply falls outside its intended range.

---

🔌 NON-ISOLATED DESIGN

Galvanic isolation:

No

The input and output circuits are not galvanically isolated from one another.

⚠️ IMPORTANT: If your installation requires electrical isolation between the 24V input circuit and 12V-class output circuit, select an appropriate isolated converter instead.

---

🔩 6.3MM FASTON CONNECTIONS

The Orion uses 6.3mm Faston tabs for its DC electrical connections.

The supplied product information states that delivery includes four insulated female 6.3mm Faston crimp terminals.

This provides the mating terminals required for connection to the converter.

⚠️ IMPORTANT: Faston terminals must be correctly crimped and the cable itself must be sized according to current, cable length, voltage drop and circuit-protection requirements.

---

🔋 LOW OFF-LOAD CURRENT

Supplied off-load current:

<15mA

This represents current consumed while the converter remains powered without supplying a significant connected load.

The effect of this standby consumption should be considered if the converter remains connected to a battery system for extended periods.

---

🌡️ OPERATING TEMPERATURE RANGE

Operating temperature:

-20°C to +55°C

Fan-assisted cooling:

No

The converter is designed to operate across the supplied temperature range without temperature-controlled fan assistance.

⚠️ IMPORTANT: Install the converter where heat can dissipate appropriately and avoid mounting it adjacent to exhaust systems, engines, heaters or other major heat sources.

---

🏠 IP20 – PROTECTED INSTALLATION REQUIRED

This Orion converter is identified as IP20.

It should therefore be installed in a dry, protected environment and must not be treated as weatherproof or water-resistant.

⚠️ IMPORTANT: Do not expose an IP20 converter to rain, water spray, wash-down or other direct environmental exposure.
